弹性键连接在传递扭转力矩时,可降低动载荷和减小振动。如图所示,它内轴3和与其间隙配合的齿轮1和键2组成。轴上矩形键槽的深度较键的直径大些,并用垫圈4固定,防止轴向移动。连接时,两端反向弯曲的键杆装 Flexible key connection in the transfer of torque, can reduce the dynamic load and reduce vibration. As shown in the figure, it consists of an inner shaft 3 and a gear 1 and a key 2 engaged with a clearance therebetween. The depth of the rectangular keyway on the shaft is larger than the diameter of the key and is fixed by a washer 4 to prevent axial movement. When connected, both ends of the reverse bending of the key installed
